Heidi Planck

Case Information:

Heidi Planck was 39 years old when she disappeared from the Hope Flower apartment complex in Downtown Los Angeles on October 17, 2021. She had attended her son’s football game earlier that day but left abruptly before the game ended.

Later that evening, her labradoodle, Seven, was found alone on the 29th floor of the high-rise building. Security footage captured Heidi entering the building, but there is no record of her ever leaving the premises.

Case Details:

Investigators focused heavily on the apartment building’s trash chute system after a search of Heidi’s home revealed no signs of a struggle. Her 2017 Range Rover was discovered parked nearby with her personal belongings still inside.

In late 2021, authorities spent weeks searching the Chiquita Canyon Landfill in Castaic. They believed her remains might have been transported there via the building’s waste disposal system. While significant evidence was gathered, the search did not lead to a physical recovery.

Timeline of Events:

On October 17, 2021, Heidi was seen at a youth football game in Downey, California. By 6:00 p.m., her dog was discovered wandering the halls of a Downtown Los Angeles high-rise where Heidi did not live.

Her family reported her missing when she failed to pick up her son from school the following day. By October 20, the LAPD had officially taken over the case, noting several inconsistencies in her final known movements.

Investigation:

The investigation is led by the LAPD Robbery-Homicide Division. Detectives have explored potential links to Heidi’s professional life as a controller for a local investment firm.

Federal agencies, including the Federal Bureau of Investigation, have assisted in reviewing financial records and digital footprints. As of 2026, authorities continue to seek information from anyone who was at the Hope Flower building on the night she vanished.

Community Response:

The Los Angeles community has held several vigils and awareness walks to keep Heidi’s story in the headlines. Her ex-husband and friends have been vocal advocates, pushing for more transparency from the apartment complex management.

True crime advocates often cite the “Heidi Planck” case as an example of the dangers of urban high-rise security gaps. The hashtag #FindHeidiPlanck remains a central point for digital awareness and community-led tips.

Family Statements:

Heidi’s family describes her as a “lioness” who was entirely dedicated to her young son. They maintain that she would never have left him or her dog willingly, pointing to the suspicious circumstances of her vehicle and pet.

They continue to urge the public to come forward with any cell phone footage or photos taken near 12th and Hope Streets. Their focus remains on finding answers to provide closure for her son and aging parents.

Heidi Planck is 5 feet 3 inches tall and weighed 120 pounds at the time of her disappearance. She has blonde hair and blue eyes and was last seen wearing jeans and a grey sweater.
